Description

Technical Field

Common water purifiers include polyaluminium chloride, polyaluminium ferric chloride, basic aluminium chloride, polyacrylamide, ferrous sulfate, aluminium sulfate and polyferric sulfate. Water purifiers have the characteristics of good water purification effect and fast water purification speed. Their raw materials are natural materials with adsorption capacity. During the processing of water purifiers, tail gas may be generated, and the tail gas needs to be cooled by a cooling device before being discharged.
